[j-nsp] polishing an antique m7i

[Randy Bush]

- old m7i with RE-B-1800X1-4G-S
- currently running 14.2R7.5
- hard disk dying
- have nice new 1tb sata ssd for it
- juniper support download is pushing 15.1R7.9 at me
- should i worry about increased memory use or license changes in 15?
- if so, where the heck is 14?
- and with the support portal rearrangement, i can not find destructions
  for making a bootable usb stick from install-media-15.1R7.dms (on a
  mac or an rPi, of course:) <blush>

thanks for clues
